FRAME ASSEMBLY FOR STABILIZER, AND STABILIZER

TECHNICAL FIELD

The present invention relates to the technical field of stabilizers, in particular to a frame assembly which is used for holding a stabilizer provided with a photographing device in a labor-saving manner. The present invention also relates to a stabilizer with the frame assembly.

BACKGROUND ART

It is known that existing hand-held stabilizers generally consist of a gimbal for fixing the photographing device and a frame assembly connected at one end to the gimbal for supporting the gimbal, wherein the frame is generally in the form of an upright single straight rod structure which can be gripped by a photographer for lifting the photographing portion during photographing. Since the operation keys of the hand-held stabilizer and the battery required for the operation of the hand-held stabilizer are both disposed in the frame, this tends to make the frame long. The frame with the elongated rod structure has the following problems: when the hand-held stabilizer is loaded with the camera, at least 60% of the total weight of the stabilizer and the camera may be concentrated in the camera position due to the heavy load of the camera, i.e., the overall center of gravity of the camera and the stabilizer may be a distance higher than the part where the user grips the hand-held stabilizer. The distance enables a user to spend a great deal of effort in order to balance the weight of the camera, bringing the wrist or the arm of the user an uncomfortable pressing sense; particularly photographing by using the lifting mode for a long time can be very laborious, which requires high arm strength for a photographer, and does not meet the great trend of improving the ergonomic friendliness and the user experience nowadays.

Furthermore, in the development process of the hand-held stabilizer, its overall shape has basically not changed, that is, it is constructed into a single straight rod shape, which makes the use configuration of the hand-held stabilizer very single. This cannot meet the actual needs of users wishing to hold the stabilizer in a user-friendly and easy-to-operate manner in various application environments.

Therefore, there remains a need in the field to provide a stabilizer and frame assembly thereof, which is ergonomic, changeable in use configuration and good in stability.

SUMMARY OF THE INVENTION

The present invention is directed to a frame assembly and a stabilizer with the frame assembly that at least partially address the deficiencies of the prior art described above.

According to an aspect of the present invention, provided is a frame assembly of a stabilizer, wherein the stabilizer comprises a gimbal for fixing a photographing device and adjusting an posture of the photographing device, the frame assembly is used for the gimbal; wherein the frame assembly comprises: a first frame part having a first end connected to the gimbal and a second end far away from the gimbal, the first frame part being configured to support the gimbal with its first end; a second frame part having a first end connected to the first frame part and a second end far away from the first frame part, the second frame part being configured to be disposed at an angle to the first frame part; a holding handle configured with a connection end connected to the second end of the second frame part and a holding end far away from the second frame part, wherein, based on the relative position relationship between the holding handle and the first frame part caused by the pivoting of the holding handle about the axis of the second frame part, the frame assembly is provided with a plurality of use configurations and is configured to be deformable among the plurality of use configurations.

Thus, the frame assembly according to the present invention, compared with the prior art, changes the design of the frame of the conventional stabilizer from the fundamental functional principle, and modifies the conventional single straight-rod frame into a frame assembly consisting of a plurality of parts extending in different directions. Different from the single use configuration in the prior art, this allows the frame assembly of the present invention to be provided with a plurality of use configurations and deformable among the plurality of use configurations, which allows the user to flexibly adjust the use configurations of the frame assembly according to the actual application environment to ensure that the stabilizer is operated ergonomically.

In a preferred embodiment, the plurality of use configurations comprise a first use configuration, and under the first use configuration, the holding handle and the first frame part are generally coplanar and the holding handle extends from the second frame part in a manner arranged close to the gimbal, so as to allow the stabilizer to be held via the holding handle in a manner substantially vertically aligned with an overall center of gravity of the stabilizer and a photographing device. Thereby, the user is allowed to hold the stabilizer ergonomically in a labor-saving manner.

In a preferred embodiment, the plurality of use configurations comprise a second use configuration, and under the second use configuration, the holding handle is generally orthogonal to the first frame part to allow the frame assembly to be supported via the holding handle.

In connection with FIGS. 1-3, a stabilizer 101 with a first embodiment of a frame assembly 100 of the present invention is shown. Wherein the stabilizer 101 comprises a gimbal 103 for fixing a photographing device such as a single lens reflex camera or a video camera or VR device. As shown in FIG. 1, wherein the gimbal 103 is a three-axis gimbal and comprises a three-rotating axis structure, namely a pitch axis structure, a roll axis structure and a yaw axis structure. The pitch axis structure can be used for mounting the photographing device, and as an example, a motor in the pitch axis structure can drive the photographing device to perform pitch motion around the pitch axis; the pitch axis structure is arranged on the roll axis structure, and a motor in the roll axis structure drives the photographing device to perform roll motion around the roll axis; the roll axis structure is arranged on the yaw axis structure, and a motor in the yaw axis structure controls the camera of the photographing device to rotate around the yaw axis A1. It should be noted that although a three-axis gimbal is shown in the drawing, the solution provided in embodiments of the present invention is equally applicable to a dual-axis gimbal.

As further shown in FIG. 1, the stabilizer 101 also comprises a frame assembly 100 for supporting the gimbal 103. Wherein the frame assembly comprises: a first frame part 1 extending in the direction of the yaw axis A1 of the gimbal 103, the first frame part 1 is, by way of example, generally cylindrical having a first end 11 connected to the gimbal 103 and a second end 12 far away from the gimbal 103. Where the first frame part 1 supports the gimbal 103 with its first end 11, more specifically, the first end 11 of the first frame part 1 is connected to the yaw axis structure of the gimbal 103 so as to support the overall gimbal 103. Further preferably, the first frame part 1 is provided at its second end 12 with a threaded hole for connecting with an external accessory, such as, but not limited to, a tripod, flashlight, or other fitting. Wherein the screw hole can be a general screw hole of ¼. Thereby, it is possible to allow a user to connect the external accessory such as a tripod, flashlight and the like to the frame assembly as required in a simple manner, thereby expanding the use range of the gimbal.

As shown in FIG. 1, the vertical height of the first frame part 1 of the frame assembly 100 according to the present invention is significantly reduced compared to the prior art, and as an example, the height of the first frame part 1 may be generally about one-third to one-half of the frame height of the conventional stabilizer. Preferably, the first frame part 1 uses a part of the outer peripheral surface thereof as a layout area for arranging the function keys of the stabilizer 101, preferably the function keys comprise at least the control keys of the photographing device. For example, an interface (by way of example, a USB interface or a charging interface or an SD card interface, etc.) by which the stabilizer is used for electrical connection with an external device, and operation keys (by way of example, such as control keys of the photographing device) of the stabilizer may be concentrically arranged on the left-most outer peripheral surface (hidden from view in FIG. 1, not shown) of the first frame part 1. According to the arrangement, on one hand, when the stabilizer is operated by a user, the control key of the photographing device can be operated by an idle finger when the stabilizer is held, so that the photographing of the photographing device can be controlled, which improves the user experience when the user uses the stabilizer. On the other hand, when the stabilizer is in wired electrical connection with the external device, such as a charging operation or a data connection with the external device, the external lead does not interfere with the normal operation of the stabilizer by the user, which also improves the user experience when the user uses the stabilizer.

Further, an operating knob protruding from the outer peripheral surface is disposed on one side of the first frame part 1, as shown in FIG. 1. Preferably, the operating knob is arranged adjacent to the operating key so as to allow a user to operate the operating knob also with the idle finger while holding the stabilizer. Those skilled in the art can understand that in this way, the user experience of the user can be effectively improved.

It will be understood that the first frame part 1 is made of engineering plastic or metal having a certain strength. In order to facilitate the user's grip, the outer peripheral surface of the first frame part 1 may be frosted, for example, to prevent the first frame part 1 from accidentally slipping off the user's hand.

As shown in FIG. 1, the frame assembly 100 also comprises a second frame part 2 extending in a direction perpendicular to the yaw axis A1 of the gimbal 103. Wherein, the second frame part 2 has a first end 21 connected to the first frame part 1 and a second end 22 far away from the first frame part 1, wherein the second frame part 2 supports the first frame part 1 at its first end 21. As shown in FIG. 1, as a preferred example, the first frame part 2 and the first frame part 1 may be constructed as one piece, which is manufactured by molding, for example, when the first frame part 1 and the second frame part 2 are made of plastic. As will be understood by those skilled in the art, when the first frame part 1 and the second frame part 2 are formed in one piece, it is possible to reduce the number of parts when manufacturing the stabilizer or the frame assembly and accordingly reduce the assembly cost. Of course, it will be understood by those skilled in the art that the first frame part 1 and the second frame part 2 may also be separate components connected to each other, in which case the second frame part 2 may be allowed to be connected to the first frame part 1 in such a way as to pivot about its own axial direction relative to the first frame part 1.

As an example, the second frame part 2 is of a cylindrical structure with an axis A2, with the section being a generally rectangle rounded at both ends. Preferably, the second frame part 2 is of an axisymmetric cylindrical structure with respect to its own axis A2. Wherein the width of the second frame part 2 is substantially the same as the diameter of the first frame part 1 to allow be connected to the first frame part 1 in a substantially smooth transition manner, which avoids a protruding or a step portion on the outer surface of the frame assembly 100, so that the frame assembly 100 has a good grip feel or product texture. Preferably, the second frame part 2 is provided at both the upper end face and the lower end face of the cylindrical structure thereof with soft rubber for increasing the frictional force with the hand face of the user when held by the user. As an alternative, it is also possible to form a friction-increasing texture on the outer peripheral surface of the second frame part 2.

As a non-limiting example, the second frame part 2 is configured as a battery compartment of the stabilizer 101 for accommodating the battery. Wherein the battery compartment may be designed to allow a user to open from the outside to perform a replacement operation on the battery, or may be designed to prohibit the user from opening and perform a charging operation on the accommodated battery only through the charging interface. Of course, it will be appreciated by those skilled in the art that the second frame part may be configured for other uses such as the arrangement of function keys. It will be appreciated that the second frame part 1 may be made of the same material as the first frame part 2, such as but not limited to plastic or metal.

As shown in FIG. 1, the frame assembly 100 also comprises a holding handle 3 disposed at an angle relative to the second frame part 2, wherein the holding handle 3 has a connecting end 31 connected to the second frame part 2 and a holding end 32 far away from the second frame part 2, shown in FIG. 1 as being above the connecting end 31. This allows the frame assembly to be configured to allow the stabilizer to be supported by the holding handle 3 in a manner substantially vertically aligned with the overall center of gravity of the stabilizer and of the photographing device (described in more detail below in connection with FIG. 6). Specifically, as shown in FIG. 1, the holding handle 3 may be configured as a generally circular cross-sectional cylindrical structure extending upward from the connecting end 31. A cambered surface conforming to the shape of the user's hand surface is preferably disposed at the holding end 32 of the holding handle 3 to increase the contact surface between the holding handle 3 and the user's hand surface. Further preferably, at the holding end 32 along the outer periphery surface thereof, provided is at least one operating member of the stabilizer 101, which may be, for example, a key, a dial, a toggle switch, or the like. With this arrangement, the user is allowed to operate the operating member of the stabilizer 101 with idle finger(s) while holding the stabilizer at the holding end 32, thereby improving the user experience.

Preferably, the holding handle 3 may be provided with a threaded hole at its connecting end 31 or holding end 32 for connecting with an external accessory 8 (shown in FIG. 6), such as, but not limited to, a tripod, flashlight or other fitting.

The structures of the stabilizer 101 and the frame assembly 100 of the present application are roughly described above. In order to overcome the problem of the single use configuration of the frame assembly of the stabilizer in the prior art, in the present application, the frame assembly 100 is constructed to be composed of a plurality of components that can have different relative position relationships; and based on the relative position relationship between the holding handle 3 and the first frame part 1 caused by the pivoting of the holding handle 3 about the axis A2 of the second frame part 2, the frame assembly 100 has at least a plurality of use configurations (will be described in detail in conjunction with FIGS. 6-11 hereinafter) and the frame assembly 100 is deformable among the plurality of use configurations.

The pivoting of the holding handle 3 about the axis A2 of the second frame part 2 herein may be achieved through a pivoting mechanism provided between the second frame part 2 and the holding handle 3. Of course, it is also conceivable that the above pivoting can also be achieved by pivoting the second frame part 2 relative to the first frame part 1 about its own axis A2. In the following, this will be described in detail in conjunction with a number of different examples.

In an example shown in FIG. 1, wherein the first frame part 1 and the second frame part 2 are constructed as one piece. In this case, the connecting end 31 of the holding handle 3 may be connected to the second end 22 of the second frame part 2 via a pivot mechanism 4 disposed between the holding handle 3 and the second frame part 2 in a manner of allowing the holding handle 3 to pivot about the axis A2 of the second frame part 2 by the holding handle 3, thereby allowing a user to adjust the relative position relation of the holding handle 3 relative to the first frame part 1. Different from the single use configuration in the prior art, this allows the frame assembly 100 in FIG. 1 to be provided with a plurality of use configurations and deformable among the plurality of use configurations, which allows the user to flexibly adjust the use configurations of the frame assembly according to the actual application environment to ensure that the stabilizer is operated ergonomically (deformations among use configurations of the frame assembly will be described in detail below in conjunction with FIGS. 6-11).

Specifically, the holding handle 3 can pivot about the axis A2 of the second frame part 2, thereby allowing the position relationship of the holding handle 3 with respect to the first frame part 1 to be adjusted, and therefore, the frame assembly 100 of the stabilizer according to the present application is provided with a plurality of different use configurations. For example, the frame assembly 100 shown in FIG. 1 is under a first use configuration, wherein the holding handle 3 and the first frame part 1 are generally coplanar and the holding handle 3 extends from the second frame part 2 in a manner arranged close to the gimbal 103. In the present application, that the holding handle 3 and the first frame part 2 are generally coplanar means that two straight lines as the axes of the holding handle 3 and the first frame part 2 can generally form a plane. Meanwhile, the holding handle 3 extends in a manner arranged close to the gimbal 103. In FIG. 1, the holding handle 3 extends upward as shown in the figure. By arranging the holding handle 3 close to the gimbal 103 to allow the stabilizer to be loaded with the photographing device, the stabilizer 100 can be held via the holding handle in a manner substantially vertically aligned with the overall center of gravity of the stabilizer and of the photographing device (see FIG. 6 and the description of FIG. 6 hereafter), which allows the user to operate the stabilizer 100 in a labor-saving manner.

Further, when the user pivots the holding handle 3 by 90 degrees clockwise about the axis A2 as shown in FIG. 1, at this time, the frame assembly 100 can be under a second use configuration, wherein, the holding handle 3 will be in a position substantially orthogonal to the first frame part 1 (also substantially perpendicular to the plane defined by the axis A1 and the axis A2), and the user is allowed to support the frame assembly 100 via the holding handle 3 at this time, for example, but not limited to, by resting the holding handle on a support or his shoulder, thereby reducing the user's burden (see FIG. 10 and the description of FIG. 6 hereafter), which allows the user to be operate the stabilizer 100 in a user-friendly manner.

Furthermore, when the user continues to pivot the holding handle 3 about the axis A2 by 90 degrees clockwise as shown in FIG. 1, the frame assembly 100 can be under a third use configuration at this time, wherein the holding handle 3 is substantially coplanar with the first frame part 1 and the holding handle 3 extends from the second frame part 2 in a manner arranged away from the gimbal 103. Specifically in FIG. 1, the holding handle 3 extends upward as shown in the figure. By means of extending of the holding handle 3 downwards, the frame assembly as a whole is roughly in the shape of “∩”, that is, the second frame part 2 is located in the middle, and the holding handle 3 and the first frame part 1 are respectively positioned at two ends of the second frame part 2 in a parallel and partially overlapped manner. This allows the user to hold the frame assembly 100 by co-clamping the holding handle 3 and the first frame part 1 (for example, but not limited to, via his shoulder), which not only support the stabilizer very labor-effectively, but also prevents accidental tilting or slipping of the stabilizer during operation. Thus, it is desirable to set the pivot angle range of the holding handle 3 about the axis A2 to be between 0 and 180 degrees in this application. Of course, those skilled in the art can understand that the pivot angle range of the holding handle 3 about the axis A2 is not limited to the above angles, and can be flexibly set according to actual needs.

Further preferably, as shown in FIG. 1, independently of the above-mentioned pivoting about the axis A2, the holding handle 3 can also be pivotally connected to the second end 22 of the second frame part 2 pivoted about a pivot axis orthogonal to the axis A2 of the second frame part (see FIGS. 2-3, pivot axis A3), such that the angle of the holding handle 3 relative to the second frame part 2 is adjustable. Due to this angular adjustability, the user is allowed to adjust the angle and manner in which the user holds the stabilizer frame according to the weight of the mounted photographing device and the actual application environment to ensure that the stabilizer is ergonomically operated.

Those skilled in the art can know that the above-mentioned pivoting of the holding handle 3 about the axis A2 of the second frame part 2 can be realized by a pivot mechanism, and the pivoting of the holding handle 3 about the pivot axis A3 can also be realized similarly via another pivot mechanism independent of the pivot mechanism. It is also feasible to integrate the above two pivot mechanisms into a single dual-axis pivot mechanism to reduce the number of parts of the stabilizer frame assembly. In the following, two exemplary examples of the dual-axis pivot mechanism disposed between the second frame part 2 and the holding handle 3 will be given in conjunction with FIGS. 2-3. It should be noted, however, that the above-mentioned examples are not intended to limit the scope of the present application, and that those skilled in the art can make many conventional modifications without departing from the inventive concept as set forth in FIGS. 2 and 3, which still fall within the scope of the present application.

FIG. 2 shows a first exemplary mode of a dual-axis pivot mechanism. The pivot mechanism shown in FIG. 2 comprises: a connecting plate 55 fixedly connected to the second frame part 2; wherein, the connecting plate 55 is provided with a plurality of through holes through which fasteners pass, so that the connecting plate is fixedly connected to the second frame part 2 through the fasteners disposed in the holes; and a pivot shaft 51 fixedly connected to the connecting plate 55, wherein the pivot shaft 51 is supported on the connecting plate 55, for example, in an integrated manner, although the pivot shaft 51 may also be supported on the connecting plate 55 and rotated together therewith, for example, in a gluing or welding manner. It will also be appreciated that the connecting plate 55 may be omitted, i.e. the pivot shaft 51 may be fixedly connected directly to the second frame part 2. As further shown in FIG. 2, the pivot mechanism also comprises a pivot mount 41, wherein one end of the pivot mount 41 is rotatably supported on the pivot shaft 51 for pivoting relative to the second frame part 2 about axis A2 of the second frame part. Further, also comprised is a pivot body 61 fixedly connected to the holding handle 3, which in this example is also configured as a pivot shaft 61. The pivot shaft 61 is pivotally supported at the other end of the pivot mount 41 about a pivot axis A3, wherein axis A2 of the second frame part is orthogonal to said pivot axis A3.

Specifically, the pivot mount 41 comprises: a counter bore at one end thereof for accommodating the pivot shaft 51, and a bearing portion (not shown) for rotatably supporting the pivot shaft 51 being disposed in the counter bore; and a pair of connecting arms 42 disposed at the other end of the pivot mount 41, wherein an interior space 421 is defined between the pair of connecting arms 42, thereby sandwiching the pivot shaft 61 in the interior space 421. The holding handle 3 may be sleeved on the pivot shaft 61 via a connecting ring such that the holding handle 3 is pivotable relative to the pivot mount 41 about the pivot axis A3. It follows that, by virtue of the above-described design, it is possible to pivot the pivot mount 43 about axis A2 of the second frame part and pivot the holding handle 3 about the pivot axis A3 via the pivot shaft 51.

As shown in FIG. 2, wherein one end of the holding handle 3 is provided with a fixedly connected connecting ring via which the holding handle is accommodated in the interior space 421 between the pair of connecting arms 42 in such a manner that the holding handle is fixedly sleeved on the pivot shaft 61. The undesired movement of the connecting ring and the pivot shaft 61 in the direction of the pivot axis A3 can be further prevented by the clamping action of the connecting ring 31 via the pair of connecting arms 42, so that the holding handle 3 can only pivot about the pivot axis A3. In the present example, the above-mentioned pivot mount 43 may be integrally formed, for example, by injection molding, after which the pivot shaft 51 and the pivot shaft 61 are respectively inserted into the pivot mount 43 to realize the pivoting function. Thereby, adjustment of the use configurations of the frame assembly is achieved in a simple and reliable manner.

In order to define the pivot angle range of the holding handle 3 about the pivot axis A3, preferably, also comprised is a second limiting mechanism for defining the pivot angle range of the holding handle 3, wherein as shown in FIG. 2, the second limiting mechanism comprises: a shoulder disposed at an end of the pivot shaft 61, wherein the shoulder extends on a part of the outer periphery of the pivot shaft 61 to define a limiting groove 611. As a preferred example, a plurality of threaded holes are provided on the shoulder, whereby the holding handle 3 can be fixedly connected to the pivot shaft 61 by passing threading fasteners such as screws through the threaded holes and corresponding threaded holes disposed on the connecting ring. As an example, in which the limiting groove 611 is formed such that the shoulder does not extend along the overall outer periphery of the pivot body, wherein a range of a center angle corresponding to the limiting groove 611 corresponds to a range of the pivot angle of the holding handle 3, that is, both side walls of the limiting groove 611 are formed as stopping end walls when the pivot shaft 61 pivots about the pivot axis A3. Further, the second limiting mechanism also comprises a support pin 43 fixedly disposed on the connecting arm 42 as a stopper, wherein the support pin 43 extends into the limiting groove 52 defined by the shoulder 51 so as to prevent rotation of the holding handle 3 beyond the pivot angle range thereof via fit of the support pin 43 with the stopper end walls at both ends of the limiting groove 611. By way of a non-limiting angle range, in this example, the holding handle 3 pivots within an angle range of about 120 degrees. Further, the holding handle 3 pivots within an angle range of about 90 degrees.

In a more advantageous aspect, the example shown in FIG. 2 also comprises a second locking mechanism for locking the holding handle 3 in a predetermined angular position, in order to enable the holding handle 3 to be maintained in a user-adjusted angular position, which comprises: a recess 612 disposed at an end portion of the pivot shaft 61, wherein the recess 612 can be formed by machining an opening on one end of the pivot shaft 61, although the recess 612 can be integrally formed when the pivot shaft 61 is injection molded; and a locking block 62 movable relative to the recess 612 in the direction of the pivot axis A3 between a pressed position and a released position, as shown in FIG. 2, wherein the locking block 62 is generally frustoconical and has an outer profile sized to frictionally engage and/or positive fit with the recess 612 when being in the locked position, thereby locking the pivoting of the holding handle 3 about the pivot axis A3 via the frictional engagement and/or positive fit; and an adjustment member 63 configured to actuate the locking block 62 to act between the pressed position and the released position via its own rotation. In particular, the adjustment member is a threaded member cooperated with a threaded hole in the pivot mount 41, wherein one end of the threaded member is fixedly connected with a torque wrench disposed outside the pivot mount and the other end thereof is connected to the locking block 62. During use, the adjustment member 63 is actuated to rotate via the torque wrench disposed outside the pivot mount 41 by the user, and upon rotation of the adjustment member 63, linear movement of the adjustment member 63 in the direction of the pivot axis A3 is effected via threaded engagement with threads not shown in the pivot mount, thereby actuating the locking block 62 to act between its pressed and released positions. For frictional engagement and/or positive fit, this may be achieved by selecting the coefficient of friction of the material pair of the locking block 62 and recess 612 or by providing corresponding positive fit structure on the locking block 62 and recess 612, as is known to those skilled in the art and will not be described in detail herein.

Further, in order to avoid the influence of external dust and moisture on the pivot shaft 61, when the pivot shaft 61 is inserted in place in the pivot mount 41, also comprised is a close cover closed from the outside, for example, a cover with a clip foot which is engaged with a clip groove disposed in the connecting arm 42 of the pivot mount 41 to be fixedly connected to the pivot mount 41. Preferably, a sealing ring is provided in the close cover to improve sealing against external environmental influences.

Meanwhile, in order to define the pivot angle range of the pivot mount 41 relative to the second frame part 2, preferably, the example shown in FIG. 2 also comprises a first limiting mechanism for defining the pivot angle range of the pivot mount 41 relative to the second frame part, wherein the first limiting mechanism comprises: a limiting groove disposed in the counter bore of the pivot mount 41 and extending along the circumferential direction of the pivot shaft 52; and a stopper 52 fixedly sleeved at an end of the pivot shaft 51, wherein the stopper 52 is, for example, a collar which is in a positive fit with the pivot shaft 51 and rotates in synchronization with the pivot shaft 51, wherein the stopper 52 is provided with a stopping protrusion 521 extending into the limiting groove. Thereby, the pivot angle range of the pivot mount 41 relative to the second frame part 2 is defined by the limiting action between the stopping protrusion 521 and the two end walls of the limiting groove. As a non-limiting range of angles, in this example, the pivot mount 41 pivots within an angle range of 180 degrees. Further, the pivot mount 41 pivots within an angle range of 120 degrees.

In a more advantageous aspect, also comprised is a first locking mechanism for setting the angle formed by said second frame part 2 and the pivot mount 43 (likewise, the holding handle 3) in order that the pivot mount 41 can be maintained at a user-adjusted angular position relative to the second frame part 2, wherein the first locking mechanism comprises: a clamping block 53 disposed about the pivot shaft 51 and capable of acting between a clamped position and a released position, as shown in FIG. 2, for example in the form of an open-ended dovetail, is disposed partially about the pivot shaft 51 so as to act between the released position and the clamped position under the action of an external force. Specifically, when the clamping block 53 is in the released position, the clamping block 53 is outwardly tensioned under its own tension so as not to frictionally engage the pivot shaft 51, which allows free rotation of the pivot mount 41 and the holding handle 3 relative to the second frame part 2; when the clamping block 53 is in the clamped position against its own tension under the action of the external force, the clamping block 53 prevents the pivot mount 41 from rotating about axis A2 of the second frame part via frictional engagement and/or positive-fit with the pivot shaft 51, where by the angular position of said second frame part 2 and pivot mount 41 and holding handle 3 can be set. Further, the mechanism for applying an external force may be, for example, a threaded member 54 which may be fitted with a threaded hole disposed on the pivot mount 41, wherein one end of the threaded member 54 is fixedly connected with a knob disposed outside the pivot mount 41 for operation by a user while the other end of the threaded member 54 abuts against the clamping block. Thereby, via operation of the knob by the user, an external force can be selectively applied to the clamping block, causing it to act between the clamped position and the released position, which finally results in maintaining the pivot mount 41 in a user-adjusted angular position relative to the first member 2.

Further, FIG. 3 shows another exemplary mode of the dual-axis pivot mechanism. Similar to that shown in FIG. 2, wherein the pivot mechanism shown in FIG. 3 comprises a connecting plate 55′ fixedly connected to the second frame part. A pivot shaft 51′ fixedly connected to the connecting plate 55′, wherein the pivot shaft 51′ is supported on the connecting plate 55′ and rotates together therewith. It will also be appreciated that the connecting plate 55′ may be omitted, i.e. the pivot shaft 51 may be fixedly connected directly to the second frame part 2. As further shown in FIG. 3, the pivot mechanism also comprises a pivot mount 41′, wherein one end of the pivot mount 41′ is rotatably supported on the pivot shaft 51′ for pivoting about axis A2 of the second frame part. Further, also comprised is a pivot body 61′ fixedly connected to the holding handle 3, which in this example is configured as a ball joint 61′. Wherein the ball joint 61′ is pivotally supported at the other end of the pivot mount 41′ about the pivot axis A3, wherein axis A2 of the second frame part is orthogonal to said pivot axis A3. In this embodiment, the ball joint 61′ may be a complete ball or may be a partially spherical segment or the like, as long as it is capable of being spherical contact with a corresponding clamping mount (described in more detail below).

Similar to that shown in FIG. 2, in FIG. 3, the holding handle 3 is also provided at one end thereof with a fixedly connected connecting ring via which the holding handle 3 is fixedly sleeved in the ball joint 61′ and accommodated in the interior space 421′ between the pair of connecting arms 42′. Undesirable movement of the connecting ring and ball joint 61′ in the direction of the pivot axis A3 can be prevented by the clamping action of the pair of connecting arms 42′, thereby allowing the holding handle 3 to pivot only about the pivot axis A3.

As a non-limiting example, when assembled, the connecting ring is firstly inserted into the interior space 421′ between a pair of connecting arms, and then the ball joint 61′ is placed in the connecting ring located in the interior space 421′ from one side in the direction of the pivot axis A3. The outer periphery of the ball joint 61′ is provided with threaded holes spaced apart by a plurality of limiting grooves 611′, preferably but not limited to three threaded holes in forms of limiting grooves evenly spaced apart at 120 degrees. Accordingly, the same number of threaded holes (as shown in FIG. 3) are provided along the outer periphery of the connecting ring corresponding to the aforementioned threaded holes, so that the connecting ring is fixedly connected to the ball joint 61′ by a fastener passing through the connecting ring and the ball joint 61′, thereby allowing the holding handle 3 to pivot about the pivot axis A3 via the ball joint 61′.

In a more advantageous aspect, in order to keep the holding handle 3 at a use-adjusted angle, the example shown in FIG. 3 also comprises a second locking mechanism for locking the holding handle 3 in a predetermined angular position, as shown in FIG. 3, comprising: a pair of clamping mounts 621 and 622 as locking members respectively disposed at both sides of the ball joint 61′ in the direction of the pivot axis A3, wherein the pair of clamping mounts 621 and 622 are configured to act between a pressed position and a released position in the direction of the pivot axis A3 shown in the drawings, and lock the holding handle 3 at a predetermined angular position in a frictional engagement/positive fit when the locking member is in the pressed position. Specifically, the pair of clamping mounts 621 and 622 have a spherical concave surface conformed to the outer spherical surface of the ball joint 61′ to stop the ball joint' in a frictional engagement/positive fit when the pair of clamping mounts 621 and 622 are pressed. Further, the second locking mechanism also comprises an adjustment member configured to actuate the locking member to act between the pressed position and the released position via its own rotation.

Preferably, one clamping mount 622 of the pair of clamping mounts 621 and 622 is configured to be expandable upon being pressed. In particular, this can be achieved by providing the clamping mount 622 with a non-closed outer periphery, i.e. the clamping mount 622 has an opening. Since the clamping mount 622 is expandable, the clamping mount 622 can be further expanded to receive the ball joint 61′ with a larger contact area when the ball joint 61′ is pressed against the clamping mount 622, which can better lock the ball joint 61′ to prevent undesired pivoting of the holding handle 3 deviated from a predetermined angular position upon external accidental action.

As shown in FIG. 3, wherein the adjustment member comprises a threaded member 63 fitted with a threaded hole in the pivot mount 41′. Same as FIG. 2, wherein one end of the threaded member is fixedly connected to a torque wrench disposed outside the pivot mount and the other end is connected to the locking member. The above-described screw member 63 is used in the same manner as in FIG. 2 and will not be described in detail herein.

Further preferably, the second locking mechanism shown in FIG. 3 also comprises: a guide sleeve 64 connected to the pivot mount 41′ via a fastener and a wedge block 65 slidable in the guide sleeve 64, wherein one end of the wedge block 65 is connected to the threaded member 63, and the other end of the wedge block 65 is pressed against the clamping mount 621 serving as a locking member in a wedge-positive fit manner; thus, when axially guided inward in the guide sleeve 64 in the axial direction of the pivot axis A3 via the screw member 63, the screw member 63 presses against the wedge 65, which in turn presses against the clamping mount 621. Due to the wedge surface engagement between the wedge block 65 and the clamping mount 621, the clamping mount 621 can be wedged in its pressed position and is not easy to rebound. When the clamping mount 621 is pressed by the wedge block 65, the ball joint 61′ is locked in a friction engagement/positive fit via the spherical concave surfaces of the clamping mounts 621 and 622, thereby locking the holding handle 3 at a predetermined angular position.

More preferably, as shown in FIG. 3, the wedging block 65 and the clamping mount 621 are provided with a male-female fitting structure cooperating with each other such that the wedging block 65 is not relatively rotatable relative to the clamping mount 621. By way of example, as shown in FIG. 3, wherein the male-female engagement structure on the clamping mount 663 is a rib protruding from the inclined surface of the clamping mount 621 forming a wedge-surface engagement, the male-female engagement mechanism on the wedge block 65 is a groove disposed on the inclined surface of the wedge block 65 to form an engagement with the rib. It should be noted that, in the example shown in FIG. 3, preferably, at least one of the above ball joint 61′, the pair of clamping mounts 621 and 622 and the wedge block 65 is at least partially made of a material selected from the group consisting of: nylon, aluminum alloy, steel and polyoxymethylene resin (POM). Therefore, through the material selection pairing, the friction coefficient on the contact surface between the ball joint, the pair of clamping mounts and the wedge block is increased, so that the locking mechanism works more robustly and reliably.

More preferably, in order to avoid the influence of external dust and moisture on the ball joint, also provided is a close cover 10′ closed from the outside as shown in FIG. 2.

In order to define the pivot angle range of the pivot mount 41′ relative to the second frame part, preferably, the example shown in FIG. 3 also comprises a first limiting mechanism comprising: the limiting groove disposed in the counter bore of the pivot mount and extending along the circumferential direction of the pivot shaft 51′; and a stopper 71′ fixedly sleeved at an end of the pivot shaft 51′, wherein the stopper 71′ has a stopping protrusion 721′ extending into the limiting groove. Thereby, the pivot angle range of the pivot mount relative to the second frame part is defined by the limiting action between the stopping protrusion 721′ and the two end walls of the limiting groove. As a non-limiting angle range, the pivot mount 41′ in this example pivots within an angle range of 180 degrees relative to the second frame part 2. Further, the pivot mount 41′ pivots within an angle range of 120 degrees relative to the second frame part 2.

In a more advantageous aspect, also comprised is a first locking mechanism for locking the pivot mount 41′ at a predetermined angular position, wherein the first locking mechanism comprises: a clamping block 81′ disposed about said first pivot shaft 42′ and capable of acting between a clamped position and a released position, the clamping block 81′ prevents rotation of the first pivot shaft 51′ about said axis via frictional engagement and/or positive fit with the first pivot shaft 51′, whereby the pivot mount 41′ can be locked in a predetermined angular position. Further, the mechanism for applying an external force may be, for example, a threaded member 54′, which may be engaged with a threaded hole on the pivot mount, wherein the threaded member is operated in the same manner as in FIG. 2, which will not be described in detail herein. Thereby, the user can selectively apply an external force to the clamping block 81′ to make it act between the clamped position and the released position, which finally results in maintaining the pivot mount 41′ in the user-adjusted angular position.

It should be noted that although the adjustment of the first locking mechanism, the second locking mechanism, etc. has been described above in terms of manual adjustment by the user, those skilled in the art will appreciate that, manual is merely an exemplary mode, and the functions described above can likewise be implemented in an automated manner and should therefore be considered to fall within the scope of the present invention. It is further noted that the features disclosed above in the different examples are independent of each other and may be implemented individually or in any combination.

As will be apparent from the foregoing, the holding handle 3 described in the first example allows a user to lock and hold the use configuration of the frame assembly according to the actual application environment, which ensure that the stabilizer is operated ergonomically, in addition to pivoting relative to the axis A2 of the second frame part and/or the pivot axis A3 so as to adjust the angle of the holding handle 3 relative to the first frame part 1 and/or the second frame part 2.

Next, a stabilizer with a second example of the frame assembly of the present invention will be described with reference to FIGS. 4-5.

Referring to FIGS. 4-5, a stabilizer 101 with a second example of the frame assembly 100 of the present invention is shown. Compared to the first example, the above-described stabilizer only differs in the structure of the frame assembly 100, and therefore the same-acting components are still shown with the same reference numerals.

The frame assembly 100 shown in FIGS. 4-5 comprises: a first frame part 1 extending in the direction of the yaw axis A1 of the gimbal 103, the first frame part 1 being, by way of example, generally cylindrical having a first end 11 connected to the gimbal 103 and a second end 12 far away from the gimbal 103. Where the first frame part 1 supports the gimbal 103 with its first end 11, more specifically, the first end 11 of the first frame part 1 is connected to the yaw axis structure of the gimbal 103 so as to overally support the gimbal 103. As in the first example, the first frame part 1 is also provided at its second end 12 with a screw hole for connecting the external accessory and has its outer peripheral surface as a layout area for arranging the function keys of the stabilizer 101. With regard to the specific structure and material of the first frame part 1, it is substantially the same as that of the first embodiment and will not be described in detail herein.

Further, the frame assembly 100 also comprises a second frame part 2 extending in a direction perpendicular to the yaw axis A1 of the gimbal 103. Wherein, the second frame part 2 has a first end 21 connected to the first frame part 1 and a second end 22 far away from the first frame part 1, wherein the second frame part 2 supports the first frame part 1 at its first end 21. Preferably, the second frame part 2 is pivotally connected to the first frame part 1 about its own axis A2 relative to the first frame part 1. As an example, the two may be pivotally connected relative to each other via means such as a bearing member.

As an example, the second frame part 2 is configured as a battery compartment of the stabilizer 101 for accommodating batteries. It will be understood that relative to the specific construction and materials of the second frame part 1, it is substantially the same as that of the first example and will not be described in detail herein.

As a preferred example, the second end 22 of the second frame part 2 may be provided with a through-hole through which the holding handle 3 passes, wherein the holding handle 3 is accommodated in the through-hole in such a manner that its insertion depth thereof in the through-hole is adjustable. This can be achieved, for example, by varying the inner diameter of the through-hole (i.e. the tightness of the through-hole is adjustable). As a result, it is achieved that the holding handle 3 is fixed to the second frame part 2 in such a way that the insertion depth is adjustable in the event that the angle of the holding handle relative to the second frame part 2 is not adjustable. In the example shown in FIGS. 4-5, optionally, by means of the pivoting about its own axis of the second frame part 2 between the first frame part 1 and the second frame part 2, the relative position relationship between the holding handle 3 and the first frame part 1 can be adjusted by the holding handle 3 and the second frame part 2 together, so that the frame assembly can be flexibly deformed among the plurality of use configurations by the user according to the actual application environment (the use configuration in FIGS. 4-5 is the same as the use configuration mentioned above, and will not be described in detail herein) to ensure that the stabilizer is ergonomically operated (deformation about the use configurations of the frame assembly will be described in more detail below in connection with FIGS. 6-11).

As another preferred example, as shown in FIGS. 4-5, wherein the frame assembly 100 may also comprise an index locking mechanism 7 configured to allow the holding handle 3 to pivot about the pivot axis A3 orthogonal to the axis A2 of the second frame part and disposed between the second frame part 2 and the holding handle 3, wherein the index locking mechanism is configured to be connected at one end thereof to the second end 22 of the second frame part 2. As shown in FIG. 5, the index locking mechanism 7 is also provided with an adjustment member 73 for actuating the index locking mechanism 7 to act between the engaged position and the disengaged position, preferably the adjustment member 73 is an adjustment screw. When in the disengaged position, the index locking mechanism 7 can rotate relative to the second frame part in an index adjustment manner, so that the angle formed by the second frame part 2 and the holding handle 3 can be adjusted in an index adjustment manner. Thereby, an angular adjustment between the second frame part and the holding handle can be achieved, so that the stabilizer can be operated ergonomically.

Specifically, as shown in FIGS. 4-5, the index locking mechanism 7 comprises a generally hook-shaped locking member 7 having a hook portion 72 at one end, wherein the hook portion 72 of the locking member 7 is sized to allow the holding handle 3 to pass in such a manner that the insertion depth is adjustable, as shown in FIG. 5, in which the insertion depth of the holding handle 3 is adjustable by providing a tightness adjustment member 74 for the hook portion 72, and the manner in which the adjustment member 74 adjusts the insertion depth has been described above and will not be described in detail herein. Further, the end of the locking member 7 far away from the hook portion 72 is configured with a second end face fluted disc 71 engaged with the first end face fluted disc 23 disposed at the second end 22 of the second frame part 2. The adjustment member 73 passes through the first and second end face fluted discs 23 and 71 and adjusts the interval between the first and second end face fluted disks 23 and 71, for example, in a screw feed motion. When the adjustment member 73 is unscrewed outwardly, the spacing between the first end face fluted disc 23 and the second end face fluted disc 71 becomes larger so that the locking member 7 is in the disengaged position, which allows the locking member 7 and the holding handle 3 therein to pivot relative to the second frame part 2 so as to adjust the angle formed by the second frame part 2 and the holding handle 3 in an index adjustment manner. When the adjustment member 73 is screwed inwardly, the spacing between the first and second end face fluted discs 23, 71 becomes smaller so that the locking members 7 is in the engaged position with each other, which allows the locking members 7 and the holding handles 3 therein to pivot relative to the second frame part 2 so as to maintain the adjusted angle between the second frame part 2 and the holding handles 3. Thus, it can be seen that adjusting the angle formed by the second frame part and the holding handle in an index adjustment manner can be accomplished via engagement of the first end face fluted disc 23 and the second end face fluted disc 71. Further, as shown in FIG. 4, the first end fluted disc 23 is pivotally connected to the second frame part 2 relative to the second frame part 2 about its axis A2, which may be achieved, for example, by having the second end 22 of the second frame part 2 with the first end fluted disc 23 pivot relative to the axis A2 of the second frame part 2. Thereby, in the case that the angle between the holding handle 3 and the second frame part 2 is allowed to be adjustable, the angle between the holding handle 3 and the first frame part 1 is also allowed to be adjustable, which further allows the user to operate the stabilizer ergonomically.

Although the index locking mechanism is shown in FIGS. 4-5 as being formed as intermeshing end face fluted discs, it will be appreciated that the indexing locking mechanism may also be implemented as a positive fit. For example, but not by way of limitation, the index locking mechanism may be implemented by means of a manual pin and a plurality of pin holes disposed in an indexing manner on the second frame part 2, wherein the manual pin may be locked in one of the pin holes via the action of a biasing spring to effect the index adjustment. Similar structures have been clearly described above and will not be described in detail herein.

It should be noted that although the adjustment of the locking mechanism, the index locking mechanism, etc. has been described above in terms of manual adjustment by the user, those skilled in the art will appreciate that, manual is merely an exemplary mode, and the functions described above can likewise be implemented in an automated manner and should therefore be considered to fall within the scope of the present invention. It is further noted that the features disclosed above are independent of each other and may be implemented individually or in any combination.

The operation of the stabilizer according to the present invention in a first use configuration will be described below with reference to FIG. 6.

As described above, in the prior art, in which a stabilizer of a photographing device such as a camera is installed, and due to the large mass of the camera, a problem that the overall center of gravity of the stabilizer and the photographing device may deviate from the external support point of the arm or wrist by a certain distance and excessive labor would exist. In particular, as the professional requirements for photographing become higher and higher, the mass and size of the stabilizer with the photographing device are increasing, which further exacerbates the problem that the overall center of gravity of the stabilizer and the photographing device may deviate from the external support point of the arm or wrist by a certain distance and cause excessive labor.

As shown in FIG. 6, the stabilizer according to the present invention modifies an existing straight rod frame into a multi-section frame assembly so as to allow the holding stabilizer to be aligned substantially vertically with the overall center of gravity of the stabilizer and the photographing device via the holding handle, thereby substantially eliminating or completely eliminating the problem that the overall center of gravity of the stabilizer and the photographing device deviates from the external support point. As shown in FIG. 6, the photographing device 102, for example, a single lens reflex camera, is firstly mounted on the stabilizer described herein, and the use configuration of the stabilizer is described herein in low height camera tracking shots, but it will be understood that the stabilizer is not limited to operation of low height camera tracking shots.

During the low height camera tracking shots, in order to ensure a better camera viewing angle, the camera is installed as far forward as possible, which causes the overall center of gravity of the stabilizer and the photographing device (shown by the overall center of gravity line A4 of the stabilizer and the photographing device) to be further moved forward as shown in FIG. 6. If the straight rod frame in the prior art is used, the distance between the outer support point and the overall center of gravity line A4 is increased. With the stabilizer herein, it is possible to first lay the stabilizer flat in a position such that the first frame part 1 lies roughly parallel at a height from the ground, in which case the second frame part 2 is oriented substantially vertically and the holding handle 3 is oriented roughly transversely (at this time, as shown in FIG. 6, the holding handle 3 and the first frame part 1 are substantially coplanar, and the holding handle 3 extends from the second frame part 2 in a manner arranged close to the gimbal 103). At this time, the insertion depth of the holding handle 3 relative to the second frame part 2 can be adjusted accordingly to ensure that the holding end of the holding handle 3 extends beyond the overall center of gravity line A4, depending on the forward movement of the overall center of gravity line A4 of the stabilizer. At this time, the user can hold the stabilizer in such a manner that the grip portion on the holding handle 3 is substantially collinear with the overall center of gravity line A4 (i.e., hold the stabilizer in a manner substantially vertically aligned with the overall center of gravity of the stabilizer and the photographing device) after several trial grips. After determining the proper position of the grip portion on the holding handle 3, the user can straighten the arm so that the arm, the wrist, and the overall center of gravity line A4 of the stabilizer and the photographing device are aligned. Under the condition, due to the fact that the distances among the overall center of gravity of the stabilizer and the photographing device and the arm and the wrist generally do not exist, the user can hold the stabilizer 3 for photographing in a labor-saving manner, greatly improving the ergonomic friendliness of the stabilizer, and improving the user experience.

Further, other usages of the stabilizer under the first use configuration herein are further described in conjunction with FIGS. 7-9.

FIGS. 7-8 show another usage of the stabilizer 100 under the first use configuration, which is preferably suitable for mid-height camera tracking shots. When the stabilizer 100 has been under the first use configuration, an external accessory, such as a tripod, connected to the second end 12 of the first frame part 1 is opened and the stabilizer is laid flat in a position such that the first frame part 1 lies roughly parallel at a height from the ground. At this time, the user determines the most appropriate grip position on the holding handle 3 according to the approximate positions of the overall center of gravity line of the stabilizer and the photographing device in trial grips manner as well. Furthermore, the tripod 8 in the opened state is abutted against the body of the user, so that on the one hand, undesired shaking of the stabilizer during operation is eliminated by the body; on the other hand, it is also possible to partially support the weight of the stabilizer via the frictional force of the body with the tripod 8. At the same time, the user can also carry the first frame part 1 of the frame assembly from below via his other hand to further support the weight of the stabilizer. And in this operation state, the other hand of the user can conveniently operate the function keys arranged on the first frame part 1. Therefore, this use configuration also has good ergonomic friendliness, facilitating the improvement of user experience.

FIG. 9 shows another yet usage of the stabilizer 100 under the first use configuration, which is preferably suitable for high height camera tracking shots. When the stabilizer 100 has been deformed into the first use configuration, an external accessory, such as a tripod, connected to the second end 12 of the first frame part 1 is closed and the stabilizer is placed in a place generally vertically at a height from the ground. At this time, since the overall center of gravity of the stabilizer and the photographing device is substantially in the vertical direction, the stabilizer can be held in a labor-saving manner by gripping the external accessory. Meanwhile, preferably, the holding handle may be pivoted to a position generally parallel to the first frame part, thereby allowing the other hand of the user to perform an auxiliary grip from the right side thereof. In this operating state, the other hand of the user can conveniently operate the function keys arranged on the holding handle 3. Therefore, this use configuration also has good ergonomic friendliness, facilitating the improvement of user experience.

FIG. 10 shows a second use configuration of the stabilizer 100, which is preferably suitable for high height camera tracking shots. Under the second use configuration, an external accessory, such as a tripod, connected to the second end 12 of the first frame part 1 is closed and the stabilizer is placed in a place substantially vertically at a height from the ground. At this time, as shown in FIG. 10, the holding handle 3 may be pivoted to a position generally orthogonal to the first frame part 1, thereby allowing a user to place the holding handle 3 on the user's shoulder and support the stabilizer 100 using his shoulder. This can reduce the fatigue and discomfort of holding the stabilizer for a long time. It follows that, under the second use configuration of the stabilizer 100, it is possible to allow the user to support the stabilizer in a very labor-saving manner, which is advantageous for improving the user experience.

The third use configuration of the stabilizer 100 is shown in FIG. 11, which is preferably suitable for high height camera tracking shots. Under the third use configuration, the holding handle 3 can be pivoted to the position generally coplanar with the first frame part 1 as shown in FIG. 11 and the holding handle 3 extends from the second frame part 2 in a manner arranged away from the gimbal 103 (in FIG. 11, the holding handle 3 extends downward), so that the frame assembly 100 as a whole is roughly in the shape of “∩”, that is, the second frame part 2 is located in the middle, and the holding handle 3 and the first frame part 1 are respectively positioned at two ends of the second frame part 2 in a parallel and partially overlapped manner. This allows the user to support the stabilizer in the form of a clamping shoulder, which not only support the stabilizer very labor-effectively, but also prevents accidental tilting or slipping of the stabilizer during operation. Therefore, this use configuration also has good ergonomic friendliness, facilitating the improvement of user experience.

From the above description, it can be seen that the frame assembly according to the examples of the present invention has a variety of use configurations, and can be flexibly switched and deformed among the above use configurations. Therefore, the frame assembly according to the example of the present invention can easily satisfy user needs in different application environments, greatly enhancing the user experience.
